What is M Sand

M Sand Meaning

Manufactured Sand is an excellent replacement for natural river sand. It is crushed fine aggregate produced from a source material and designed for use with concrete in construction. Production generally involves crushing, screening and possibly washing.

 

What is M Sand? – Exploring the Meaning of M Sand

“Necessity is the mother of all invention”

The Story 
High demand for sand in a booming construction sector makes it a prized possession. Good quality of concrete is always looking for high-quality sand and river sand does not always hold the answer. Manufactured sand comes as an alternative for river sand. It has many popular names across the globe such as Crushed sand, Rock sand, Greensand, UltraMod Sand, Robo sand, Poabs sand, Barmac sand, Pozzolan sand etc.

The Production

This is the section where everything matters including quality. Manufactured sand can be produced in many ways with the facility of making it available nearby construction sites. These ways are getaways to readily available sand making it much economical and pocket-friendly. 

In most of the cases, manufactured sand is produced with the help of Vertical Shaft Impactor (VSI). It is essential to reduce the particle size to get the desired properties of sand by producing equidimensional shape during the production. In case of manufactured sand, all the processes are done in a controlled environment resulting high-quality fine aggregates.

The Effect

This sand is well graded and available in the required proportion.

The absence of organic and soluble compound that affects the setting time and properties of cement is making it a better choice over the river sand if one is looking to maintain the strength of concrete.

The absence of impurities such as clay, dust and silt coatings is helping manufactured sand with increased quality and durability of concrete.

Manufactured Sand is obtained from a high-quality hard rock i.e. granite using the top end International technology which is well supported by modern machines to ensure required grading zone for the sand.

Technically manufactured sand must conform to the requirements of Zone-II as per IS 383-1970 and particles finer than 75 µm shall not exceed 15 %. Manufactured sand producers must put Special efforts such as washing of sand by water or dry washing by air in order to restrict particles finer than 75 µm to 15%. Following international norms and global trends will prove beneficial for the producer at the end of the day. 

As per the people who lead the construction sector such as – Civil engineers, Architects, Builders, and Contractors agree to the fact that the river sand, is lacking in many ways in comparison to manufactured sand.

Presence of other impurities such as coal, bones, shells, mica and silt etc shortens the life of the concrete.

The Requirements

  • Each and Every sand particle should have higher crushing strength
  • Smooth surface texture of the particles are needed
  • The edges of the particles should be grounded
  • Organic impurities are strictly not allowed
  • Silt in sand should not be more than 2%, for crushed sand

The Tests

Owing to the demands of highest standards of national and international authorities manufactured sand and must undergo the following quality tests

  • Sieve analysis
  • Optical Microscopic Study to check the particle shape
  • Slump test that measures workability by slump cone method
  • Cube test for compressive strength
  • Tests for Silt and clay

Quality of Aggregates

Aggregates must consist of naturally occurring stones, gravel, and sand. Overall these must be strong, durable, clear and dense. Moreover, it should be free from disintegrated pieces, alkali, vegetable matter and other deleterious substances.

Silver Sand is an extremely reputable organization which holds the vision of creating a customer-centric quality production of manufactured sand thus becoming customer’s most favored choice.
